What Is Ammonium Sulfate?

Ammonium Sulphate ((NH₄)₂SO₄) is a nitrogen and sulphur fertilizer containing 21% N and 24% S. It is produced as a by-product of coking, caprolactam, and acrylonitrile manufacturing, and is available as a granular or crystal product. Its ammonium nitrogen has a soil-acidifying effect, making it a preferred nitrogen source on high-pH and calcareous soils where nitrate-form nitrogen may be susceptible to loss. The sulphate sulphur is immediately available to plants.

Ammonium Sulphate in Blending and Agronomy

In fertilizer blending, ammonium sulphate is used as a supplementary nitrogen carrier when sulphur is a required component of the blend. It is particularly important in canola, onion, garlic, and other sulphur-demanding crops where deficiency can severely limit yield. As a standalone product, it is applied as a basal or topdress nitrogen on alkaline soils where urea’s efficiency may be reduced. In tropical and subtropical regions where sulphur leaching occurs, ammonium sulphate provides a sustained sulphate supply.
